I have degenerative discs in my lower back so much of my exercise is based on the back methodology I follow. I stopped running due to my bad knee to hold off replacement. Flare ups of either of those can shut me down. Then freak things like a strained upper hammy can play havoc as well. Just restarting exercise today after talking to PT. Limited walking if not too fast, too far.

Exercising for my 1st 45 years was really important to me. One reason in my early 20's I began to run. I smoked and was overweight. I quit smoking after a year because obviously running daily and smoking it was evident one had to go and if course smoking went. From then on I ran 6 miles every morning 5 days a week and 10 miles on Saturday for over 20 plus years. I fell in love with it because I had played football in Highschool and was certainly familiar with exercise. I was fortunate to not have blown out a knee or seriously injured myself because the major amount of it was outside.

Fast forward to today and the last 30 years haven't been like the first 40. Currently as of the last few days most likely because of my weight and misbehaving I find myself the last week or so short of breath just doing regular daily
activities. So this current health issue is deffinitely interfering with exercise which I want doing prior years anyway.

So bottom line to the question at hand is first my weight was so high and after a couple of years I didn't exercise then I began my bi-pap prescription and thought I'd grey back with it but never did. I shouldn't say never because I did walk with a friend for almost a year 3 days a week. I also ww's getting some exercise in my work. Deffinitely at age 72 heath issues have begun to effect exercise.

Kind of a bit of all. Stenosis starting at the top of the spine and from the bottom. My guy kids that it'll fuse itself. Of course that leads to some sciatic pain, and flexibility issues, and pulling one hip upwards, requiring a lift in my right shoe. Still have a lot of arthritis around the knee replacements, but, when I CAN walk, I feel better.
I try to do flexibility stretches daily, some light dumbbell lifting and flex band work every other day. Have shoulder issues also, so the last three help them also.
I do what I can to be seen, and not viewed.

Arthritis in my left knee has stopped any running of significance as of April 2018. I am able to do a few 1 minute at a time running intervals on the treadmill a couple times a week but can feel stiffness in the knee if I try to do more. Biking doesn't bother my knee at all so I do a lot of that! Hiking is also fine as long as there isn't too much climbing. I teach a weight training class to my residents at the retirement community on Tuesdays and Thursdays this semester. My wacko schedule and subsequent exhaustion this semester is working against me for being able to get to the weight room on a regular basis to lift something heavier than 5lb dumbbells.

I used to swim but am so time limited these days that I haven't been in the pool at all this year.

I do have asthma and like to think that the medications I take make my lungs perfectly normal. But then I periodically have to test our spirometry equipment in the lab like I did yesterday afternoon. I have mild obstructive disease. I think my numbers were worse than this time last fall. Sigh. I think I read that about 10% of people with asthma (had it since my teens) go on to develop COPD. I've seen first hand the struggles my residents with COPD have. But I also had an amazing resident with COPD several years ago that would come in and work out with a oxygen unit in a waistpack. He was such an inspiration! He passed away unexpectedly but presumably peacefully in his home one day. He had seemed fine the day before.
